Pink screen after Xenith Firmware 1.7 upgrade

I ran into this after upgrading our Wsye Xenith from 1.6 to 1.7 firmware. We were using the AutoSignoff=yes Shutdown=yes commands in our ini and after users devices were powered down then up again were seeing this.  Ironically, it didn't occur on the Xenith Pro's.

To reproduce:

1. Apply firmware 1.6

2. Upgrade to 1.7

3. Shutdown from Wyse Toolbar

4. Power on and the issue occurs

To resolve:

1. While shutdown, pull power supply

2. Start up.

OR add this to your xen.ini or wnos.ini

AutoSignoff=yes Shutdown=yes
ShutDown=turnoff 

This appears to be a known issue with no good documented solution so hopefully this helps.
